When a standard Redmi Note 9 Pro call disappears after a system update or an accidental user action, the smartphone becomes an expensive toy without the ability to make calls, which is critical for modern humans, and most often the problem lies not in physical damage, but in the software failure of the MIUI shell or the concealment of the system application.
Recovery doesn't usually require complex manipulation of superuser rights or reflashing of the device, but in most cases, it's enough to perform a series of sequential actions in the settings menu or use special commands, and it's important to act methodically, checking each step so as not to aggravate the situation.
In this guide, we’ll look at all possible scenarios, from banal icon hiding to full call reset. You’ll learn to distinguish between software interface glitches and real-world system file damage. Xiaomi Redmi Note 9 Pro has a powerful architecture, but sometimes requires manual intervention to properly work the basic functions.
Checking the availability of the system application in the menu
The first thing to do before you sound the alarm is to make sure that the app is actually removed or disabled. Often users accidentally hide the icon in folders or transfer it to a hidden partition, thinking that the program has disappeared. Android allows you to hide standard desktop cleaning utilities, but they continue to function in the background.
Go to your device settings and find the section that manages installed programs. In the MIUI shell, the path may differ depending on the firmware version, but the logic remains the same. You need to find "All applications" or "Application management".
In the list that opens, look carefully at all the programs installed, look for an app called Phone or Calls, and if you see it on the list, it means that the call itself has not gone away, and the only problem is the display of the icon on the desktop.
- 📱 Open Settings and go to the "Applications" section».
- 🔍 In the search bar, enter the word “Phone” or “Dialer».
- ⚙️ Click on the found application to open its detailed description.
- ✅ Check if the Start or Open button is active».
If an application is found but not running, try pressing the Start button. If the system issues an error or suggests removing updates, this will indicate that the cache files or the program itself are damaged, in which case proceed to the next section of the instructions.
Cleaning the cache and data of the phone application
The most effective way to resolve software conflicts is to clean up the accumulated data. Over time, call databases and logs can get corrupted, leading to a faulty interface or a complete app failure. This is a standard maintenance procedure that does not delete your contacts if they are synchronized with your Google or Mi Cloud account.
To do this, you'll need access to the application management menu. Search the "Phone" list (usually with a green or blue handset icon). Select "Memory" or "Storage" inside the menu, and you'll see two buttons here: "Clear cache" and "Clear everything."
⚠️ Warning: Using the Clear All feature will reset your call settings to factory calls, and can also clear your call log.Make sure important numbers are saved in contacts, not just in history.
It's recommended to start by cleaning the cache, which is safe and often solves the problem of the interface freeze, and if that doesn't work, use a complete data cleanup, and then the system will recreate the configuration files you need.
☑️ Checklist for data cleanup
Once cleaned, try restarting the device, which is necessary to re-initialize the communication components for system services, and in most cases, on the Redmi Note 9 Pro, this action returns the stability of the communication module.
Recovery of Remote Applications via GetApps
If you don't find a standard call in the app list, it may have been deleted by the user or damaged during the update.There is a built-in GetApps app store in the Xiaomi ecosystem that allows you to restore system components without having to download. APK-files from questionable sources.
Open the GetApps store on your smartphone. Type in "Mi Dialer" or "Xiaomi Phone" in the search bar. The official app is usually marked with a developer icon "Xiaomi Inc." or "MIUI." Make sure you're downloading the system component, not a third-party replacement.
The installation process is simple: click the “Install” or “Update” button if the system offers to update the existing version. Once you have finished downloading and installing the icon should automatically appear on the desktop or in the menu of all applications.
| Parameter | Description | Recommendation |
|---|---|---|
| Source | GetApps / Google Play | Only official shops |
| Name of name | MIUI Dialer / Phone | Check the developer |
| Size | Usually 50-100 MB | Depends on the MIUI version. |
| Permits | Contacts, Microphone, Telephone | Mandatory for work |
What if GetApps doesn’t find the app?
Always check the developer’s digital signature before installing.
Resetting settings through the engineering menu
For more advanced users, there is a way to recover via a hidden engineering menu, which allows you to reset your phone settings without affecting your personal data, but you should use it with caution, since improper actions can lead to resetting your network settings.
To get into the testing menu, open the Phone app (if it functions or is called through voice commands) and type a special code. For Xiaomi devices, code ##4636## is often used. If the code is entered correctly, the Check menu will open.
##4636##In the menu that opens, select Phone Information. Scroll down to the end of the list, and you can find either Reset or Turn off radio, and turn it back on, and this action will restart the radio.
- 📞 Dial the code ##4636### in the dialer.
- 📱 Select the item "Phone Information».
- 🔄 Click "Switch off the radio" and wait 5 seconds.
- ⚡ Click "Enable the radio" to restart the module.
⚠️ Note: Do not change the settings in the "Configure preferred network type" section unless you are sure of your carrier's communication standards. 4G/LTE.
This method is especially useful if the problem is in the nature of a “software freeze” of the communication module when the interface is working, but calls do not pass or the application does not respond to clicks.
Removing updates and returning to the factory version
Often, problems with calling on the Redmi Note 9 Pro begin immediately after the automatic update of the component through Google Play or GetApps. The new version may contain bugs or conflict with the current version of the MIUI shell.
You'll need the App Management menu again. Find the Phone, click the three dots at the top of the screen (or menu button) and select Delete Updates. The system will alert you that all data will be deleted, confirm the action.
After removing the updates, the app will return to the state it was in when you bought the smartphone. This is a guaranteed working version that is compatible with your firmware. After that, it is recommended to go to the settings of the app store and disable auto-update for this particular component, so that the problem does not happen again.
💡
If the Remove Updates button is inactive, try first pressing the Stop app and then checking the menu again.
After the rollback version, be sure to restart the device. The system must correctly integrate the factory version of the call. If after that you still want to use the new version, wait for the official patch from Xiaomi or Google.
Alternative solutions and third-party calls
If you can't get your phone back up by regular methods, or if you're just not happy with the standard call functionality, you can always install an alternative app. Google Play Store offers a lot of quality replacements that can work more stable on your version of Android.
One of the most popular solutions is Google Dialer, which is often pre-installed but hidden, and can be activated as the default app, and Truecaller's solutions, which combine calls with a number detector and spam protection, are also popular.
To install a third-party call download APK-If you have a file or find an app in the store, Android will ask permission to use the app as its primary call, confirm the request, and now all incoming and outgoing calls will be handled by the new app.
- 📲 Download Google Phone or Truecaller from Play Market.
- 🔐 Give the necessary permissions at the first launch.
- ⚙️ Go to Settings. → Annexes → By default.
- 📞 Select the installed application in the "Phone" item».
Using third-party solutions often provides a more user-friendly interface and better integration with Google contacts. However, it is worth considering that some MIUI features, such as recording conversations or specific gestures, may work differently or require additional customization.
💡
Third-party calls are not only a replacement, but often a way to bypass the bugs of the MIUI system application, as they use their own databases and engines.
